More particularly the new shapefacilitates the arrangement of the teeth in the mouth in a 'inore orless downwardly curved arch. In

addition, much fewer shapes of teeth need beheld in stock thanheretofore. It will be seen further from the drawing that both the newupper and lower incisors can be applied not only in combination with oneanother but also with opposing teeth of other shapes.

What I claim as my invention is In artificial dentures, an'upper incisorhaving a substantially horizontal plane masticating surface and anopposed lower 1nc1sor having on its labial side a front surface proper,a biting edge adapted to engage the masticating surface of 'the upperincisor, and aninclined surface extending from said biting edge downwardto the front surface proper and forming with the latter an obtuse angle.1 p

In testimony whereof, I afiiX my signature.
